Planning
The aim for my experiment is to investigate how a small piece of potato affects the rate of reaction with hydrogen peroxide.
For this investigation the following could be changed could changed:
·Concentration or hydrogen peroxide
·Surface area of potato
·Temperature
·Mass of potato
·Catalyst
The following could be measure and observed:
·Time
·Size of Potato
I am going to be changing the concentration of hydrogen peroxide. The volume will be 30ml so water …showed first 75 words of 491 total…

…showed last 75 words of 491 total…ml of hydrogen peroxide. This may be because the gas managed to escape causing the reaction to slow down.
To improve the experiment, I could measure the amount of hydrogen peroxide more accurately to ensure it is a fair test. I could also do more repeats of the experiment to get better averages.
Another experiment I could do next is to see what affect the surface area of potato has on the rate of reaction
